vansant, former fbi profiler to help us talk more about this. and clint, as we're learning about this, i know we talked when we were watching the breaking news details unfold out of aurora. this is hauntingly similar, to hear about somebody that may have been wearing camouflage. people are reporting may have been in body armor, walking into a crowded mall and starting to fire at random. >> i think that is part of the challenge with us, thomas, is that it's so similar. we know when you and i talked at that time too we had a similar weapon, an ar-15. at this time, the shooter had a 100-round magazine that jammed on him. there are early reports right now that an ar-15 with a full magazine, whether that means 10, 20 or if it's a banana clip 30 rounds, nonetheless was found laying in this mall. as you suggest, the individual is allegedly wearing camouflage clothing, body armor, and a mask described by some as a hockey mask, or something like in the movie "jason" that that individual would have been wearing at the time. we've also heard anywhere from 20 to 60 different rounds have been fired.
